“…The continuous action of wind and waves, the sediment movement, and associated sea level alterations cause a constant and progressive change on the coasts. The rise of the global sea level over the last centuries, in combination with the relevant projected rise of about 1 m by 2100 [25], will inevitably trigger severe flooding incidents and soil erosion along the shores [26,27].…”

Geophysical prospecting methods have been extensively used to outline buried antiquities in terrestrial sites. Despite the frequent application of these mapping and imaging approaches for the detection of archaeological relics in deep-water marine environments (e.g., shipwrecks), the aforementioned processes have minimal contribution when it comes to understanding the dynamics of the past in coastal and shallow aquatic archaeological sites. This work explores the possibilities of multicomponent geophysical techniques in revealing antiquities that have been submerged in diverse shallow coastal marine environments in the eastern Mediterranean. A group of four sites in Greece (Agioi Theodoroi, Olous, Lambayanna) and Cyprus (Pafos) spanning from prehistory to Roman times were chosen as test sites to validate the efficiency of electrical resistivity tomography, magnetic gradiometry, and ground penetrating radar methods. The comprehensive analysis of the geophysical data completed the picture for the hidden archeological elements in all the sites. The results manifest the significance and the potential of these methods for documenting and understanding the complex archaeological sites encountered in the Mediterranean. In view of climate change and the risks related to future sea level rise and erosion of low-level coastal areas, the results of this work could be integrated in a strategic framework to develop an effective interdisciplinary research model that can be applied to similar shallow water archaeological surveys, thus substantially contributing towards cultural resources management.

“…The length of the river is 500 km and with a projected drainage area of about 34,842 km 2 , which is nearly 1% of the total terrestrial area of India (Maurya et al 2021). On the north-west, it is bordered by the Aravalli hills and on the east, it is surrounded by the ridge that divides it from the Chambal basin.…”

Understanding the trend in seasonal precipitation in the context of climate change is crucial for the maintenance of regional water resources management. The present study examines the seasonal precipitation trend in the Mahi River basin, India by using the wavelet transform and clustering method. Very limited studies have been carried out over the basin using this approach. Daily gridded rainfall data (0.25°×0.25° spatial resolution) for 51 grids from 1970 to 2020 has been taken from India Meteorological Department (IMD) and the time series trend was tested by Mann-Kendall. The monthly, seasonal, and annual statistic has been analyzed for 51 years. We have also plotted the relationship of precipitation trend–elevation. After that, homogeneous precipitation regions are delineated with hierarchical clustering analysis. Results reveal that seasonal precipitation over the basin clusters into 4 subregions for monsoon (JJAS1 to JJAS4) and 3 subregions for winter, pre-monsoon, and post-monsoon seasons. After the regionalization of the subregions, the periodicity and the inter-seasonal relationship were analyzed using continuous wavelet transform (CWT). Findings revealed that the cross-correlation between pre-monsoon and monsoon seasons highly affect significantly in past over the basin. Further, the regional geography-altitude and moisture convergence perform a major role in the variability of seasonal precipitation. The output of the current study would be utilized in a better understanding of precipitation forecast, watershed, and agricultural planning which may give a better climate change indication at a regional-basin level. We also suggest future needs to more focus on the understanding of elevation-dependent wetting in hilly regions using a different type of datasets.

“…Inevitably, this predicted sea‐level rise in the coming decades will trigger severe flooding incidents creating scattered, vulnerable localities (Cazenave and Cozannet, 2013). Furthermore, a combination of factors including sea‐level variations, ground subsidence, waves, anthropogenic activities and land‐use changes will impose additional current and future hazards due to soil erosion along the shores (Maurya et al ., 2021).…”

Over the last three decades, multicomponent geophysical prospection has given a new perspective in the domain of inland archaeological prospection. However, the complexity and constantly evolving environmental regime encountered in the transition zones has so far limited the implementation of these technological advancements towards the understanding of the past dynamics in littoral and ultra‐shallow offshore environments. The main objective of this work is to appropriately adapt, test and validate the efficiency of diverse geophysical mapping and imaging methods for reconstructing the ancient built environment below a relatively thin water layer. The submerged prehistoric site of Lambayanna in Greece was used as an ‘open laboratory’ to explore in situ the resolving capabilities and limitations of marine three‐dimensional electrical resistivity tomography and multisensor magnetic gradiometry, as well as terrestrial ground‐penetrating radar. The geophysical mapping covered more than 4.4 hectares of the shallow marine and coastal part of the site with high spatial resolution. The data processing followed a specific flowchart to enhance the signal and the subsequent integrated analysis showed a number of candidate targets buried below the seabed, providing strong indications to support the hypothesis for the existence of an ancient submerged man‐made environment in the bay. The results demonstrate the complementary nature of applying multiple geophysical methods to under‐explored shallow offshore archaeological contexts in order to provide useful information for understanding the complex archaeological sites around the Mediterranean. The successful transfer of established geophysical methods into the ultra‐shallow aquatic environment comprises the major innovative aspect of this work. Thus, in view of climate change and the risks related to future sea‐level rise and erosion of low‐level coastal areas, the proposed research model can be integrated into a wider strategic framework for the sustainable management of coastal cultural resources.
